swollen lymphnodes in groin.

I am a 17 year old female who recieved results from an ultrasound informing me that i have swollen lymphnodes in my groin. I have had two seperate surgeries, one in may of 09 for an inguinal hurnia, and when i still had a golfball sized lump i went back to my doctor who informed me i had a second hurnia, i had my second surgery in december of 09 for a femoral hurnia. After a month of healing i felt like myself again and began working. I worked a labour job this september and when that was over i began to notice the pain again, right beneath my incision. It is very uncomfortable and seems to get worse the more physical i become. I am a new college student this year and i would not take a full course load as i feared that i had a third hurnia. The past three months have been stressful and very uncomfortable. Now i wake in the morning with pain. What are these lymphnodes doing to me? Are they disease related or cancer? Are they swollen because of the surgeries ive had? What can i do to treat this? Would a diet change fix anything? How serious is this?
